Water Quality and Water Chemistry
Maintaining water quality and water chemistry in your spa is extremely important and should be a regular part of your spa
maintenance program, as a neglected spa can be a breeding place for dangerous bacteria.
The water quality of your spa is maintained by a combination of filtration and chemistry. The spa's integral filter system
helps maintain the water cleanliness and clarity by trapping most solid materials such as hair and other debris resulting from
normal use. However, the most important part of maintaining water chemistry is keeping the proper level of disinfectant in
the water at all times. This is accomplished by adding chlorine or bromine to the water, which will control particles too small
to be trapped by the filter, such as bacteria and algae, and will oxidize any organic materials. Follow instructions provided
here, and with water quality products, for the health and safety of spa users, as well as to make your spa bathing as enjoyable
as possible.
Filtration
The filtration system of your spa will keep your water
clear and clean if used properly. We recommend that you
run your filter system for at least two hours each day. The
filter cartridge elements will trap most solid materials and
debris in the water. However, the presence of materials
such as body oils or other particles which are too small to
be captured in the filters may bring about various undesir-
able water quality conditions. These conditions can be
corrected with the use of spa treatment chemicals which
are available from your Jacuzzi Whirlpool Bath dealer.
Such conditions include the following:
Foaming: A de-foamer is available to minimize foaming of
the water. This condition is usually caused by the addition
of soaps or oils, or other fatty substances to the spa water.
The interaction of these with hot water, especially at high
pH (more alkaline) levels, will cause the water to foam.
(See Water Quality Definitions.)
Oil Film or Cloudy Water: Add clarifier to congeal oil film
on the water surface into globules sufficiently large to be
trapped by the system's filter. Cloudiness is caused by
particles that are too small to be trapped in the filter and is
also due to the presence of human body oils, lotions, and
cosmetics. During normal use, these materials can accu-
mulate on the filter element and clog its pores. The addition
of clarifier will make the water clearer, but may clog filters
which must be cleaned as prescribed under the section
entitled "Filter Maintenance" in this manual.
Hard Water: Add a de-mineralizer to break down or de-
ionize mineral particles present in the spa water.
Follow the "Filter Maintenance" procedure described in
this manual to ensure optimum performance of your spa's
filtration system.

Water Chemistry
You can ensure better water chemistry by testing your
spa water every day and adjusting the chemical balance
frequently.
Obtain a water quality test kit, designed
especially for spas, from your Jacuzzi Whirlpool bath
dealer. The test kit must be of the type which allows you
to test for the disinfectant (chlorine) level, pH, and total
alkalinity. Make sure, also, that the chemicals used in your
spa are especially for spa use, and not for swimming pool,
as water quality maintenance of spas and swimming pools
is very different.
Set up a daily program at first to check the disinfectant
level, pH, and total alkalinity of the water to familiarize your
self with the amount of chemicals to add and to determine
how often to make chemical adjustments during normal
use. Remember that the more heavily the spa is used, the
more often you should check the water chemistry.
When adding any chemicals, always run the filter
system to ensure complete dilution with the water. DO
NOT ADD CHEMICALS DIRECTLY IN THE SKIMMER
OPENING.
